It will be readily seen that our device embodies only a very few operating parts readily attached to windows of the class set forth, and its storm window opening and closin action is positive and according to 'vertic movement of the window sash. Large or small volume of air circulation is thus readily available for any room, as desired.

We claim:

1. An opening and closing device for V hingedly suspended outer window sash normally in parallel relation to slidable sash, said 7 devices comprising for each side of the window an irregularly curved, elongated actuating bar pivotally and freely suspended by its upper end from'a pin fixed in the Window frame parting strip between said .outer and the sliding sash a bracket fixed to the sliding sash and means thereon slidably engaging said actuator-bar, guide member comprising an eye screw on the outer sash slidably engaged by the actuator bar, below said fixed bracket of the slidable window sash, said actuator bar below its pivot formed in an elongated S-shape, first an inwardly directed curvature then a straight part-and its lower extremity formed in a curvature 39 reverse of the first described curvature.

' V 2. lhe structure specified in claim 1, and an actuating-bar engaging member on the said window bracket comprising a U-shaped clip straddling the actuator bar transversely and swivel mounted on the outer end part of said bracket. a

In testimony whereof we afiix our signatures. I p EDWARD O. BRAATEN. 40 I OTTO R. HARMER.
